[core/output] Add generic pango support

Browse source 
Allow any piece of a theme that specifies a set of attributes (default,
cycles, states, widgets) to use pango *instead* of the usual attributes.

If pango is present, this will have precedence.

A practical example of this can be found in the powerline-pango theme,
which is added solely for demonstration purposes.
